Description:
A weather-sealed version of the DFA 100mm f/2.8 macro lens. Maximum magnification is 1:1. The image circle of the lens covers the full 35mm film format as did its predecessor. Cosmetics have changed and build quality has been improved - the lens now has an aluminum barrel. This new lens does not have an aperture ring so it is not suitable for use on the older film cameras which do not allow for setting the aperture from the camera body, such as the LX, MX, ME, ME Super, K1000 etc.

The aperture has rounded blades which should result in a pleasing and smooth rendering of out-of-focus areas (aka bokeh).

Like all weather-sealed lenses, the D FA 100mm Macro has a rubber seal around the lens mount, which can be seen in the photo (colored red). The front element is SP (Super Protect) coated.

Pros: Sharp, 49mm filter thread, WR
Cons: No focus limiter

This lens is very sharp and has a decent bokeh. First I bought it for portraits and it worked well, but I like more the wider FoV of the DA*55, FA43. The lens is very well built and WR. Perfect for insect macros, but I feel a wider macro would be better for flowers. If the lens starts to hunt for focus it takes a long time, it goes to minimum and then back. In general I release the AF button and use quick shift to aproximetly set the focus. It's faster. A focus limiter would help, even one implemented in the firmware. This is the most well corrected pentax prime I have. No CA or PF, no distorsion, no flare.
Altough on APS-C I prefer the FA77 in general because the wider FoV.

Here are some images:

Pros: Super sharp, f/2.8, sleek design, quick-shift, weather-resistant
Cons: Screw-mount noise, focus hunts sometimes, some aberrations wide open

This lens is really great - it's produced some of my best shots!

Totally usable as a portrait lens, and a fast mid-range telephoto.

Would have been nice to have silent focusing, but the flowers and insects don't mind that too much!

Really like the WR lineup from Pentax!

Pros: Sharp, bright, 1:1 macro, excellent build quality
Cons: None!

This is quite easily the sharpest lens in my bag - just outstanding.

Nice and bright with a maximum aperture of f2.8, in a surprisingly small and light package. Great build quality with all-metal construction. The 1x magnification is ideal for macro photography.

It's also great as a portrait lens, with very pleasing bokeh.

The price of this lens is amazingly low considering the quality.

I would say this lens is one of the best in Pentax line-up. It's good not just for macro, but for portrait shots too. It is brilliantly sharp and doesn't have notable aberrations. The lens is build perfectly, looks and felt solid. The only pity - the screw-drive autofocus doesn't work good (but for macro shots it almost doesn't have any matter). Finally, the lens covers the 35mm frame, which allows you to shoot portraits in more appropriate focusing range.

Pros: Build, Sharpness, Image Quality, WR
Cons: Screw Drive AF, Autofocusing

Is this lens a limited? I have had two limiteds, the 35 and the 70, a this would be right at home with a Limited badge on it.

The metal barrel construction is great, focusing manually is a dream, perfect size (it isn’t so big you don’t want to carry it - there is alway room for this), beautiful bokeh, etc. A first rate lens on any platform, and a great lens for Pentax.

I could go on, the positives are countless.

Negatives? Screw drive autofocus and the focusing noise. AF in general with the lens hunting from end to end for what seems like eternity due to the lack of a focus limiter.

So if you can handle a few autofocusing issues, or focus manually, then you have a great lens that will product top quality images on APS-C or FF cameras. It is well worth the purchase price.

Lens Review Date: July 18, 2017 I can recommend this lens: Yes | Price: N/A | Rating: 9 

 
Pros: Image Quality, Small and lightweight, build
Cons: Slight CA, no aperture ring and focus limiter
Sharpness: 10    Aberrations: 9    Bokeh: 10    Autofocus: 9    Handling: 10    Value: 10    New or Used: New    Camera Used: K-1   

This is a must have lens for Macro on Pentax, as overall it is excellent.
The sharpness is superb as is the overall image quality.
It is small, well built, and quite light.

Only downsides are a little CA in extremis, which can be cleared up in post, the lack of a focus limiter and an aperture ring, meaning some film bodies struggle to be used with it (MZ-5n a case in point), But then again certain film bodies that can control the aperture in-body can happily use it.

So far I have only used it on the K-1, and it is a great partnership. Now to use it on film and the K-3

Really recommend.

This lens is wonderful. Compared to the older D-DA 'non-WR', the built quality is in a totally different league.
Higher quality plastic, optical elements in metal barrel, tight focusing ring, weatherproof.
For a reason I don't know, the sharpness is very, very good but slightly inferior to the older version. Probably due to manufacturing variability.
It is Very Good at full aperture, but only 'Good' in the corners. Excellent-Very Good at f/4.0, Excellent everywhere above.
Nice to use thanks to its light weight, 1:1 magnification capability and Quickshift.

Love this lens! For portrait work I can generally lock the focus and shoot at F/5.6 or F/8.0 from about 8' for a head shot.

Sharp, sharp, sharp, sharp!!! It is VERY sharp! I got my D-FA 100mm WR second hand. It is an expensive lens for our standards in Bulgaria, but all the money are worth it! Everything about that lens is beyond this world! Image quality, sharpness, build quality, rigidity, handling... it deserves 10000 stars!

Well the auto-focus is... noisy and you can literally feel when the lens is focusing. Sometime it has to go from end to end to focus, but... as a macro lens it is mainly used with manual focus, which is excellent, even with big winter gloves.

I love it and i have fun shooting with it! That's all that matters in the end of the day!

Here are some shots with K-30 and D-FA 100mm WR:

I've had this lens for a few months. Initially I was mostly using it for macro, at which it excels (surprise! Recently I've also shot sports and concerts with this lens. And it's pretty good at that too! It's not able to track over long movements towards/away from the camera, but I'd say it's more than usable within its limitations.

fwiw: the first lens I received had a problem, the focusing ring was not turning smoothly, and it's been exchanged promptly; this happens, no big deal.

I bought this lens 12 months ago and to be honest it took me a while to learn how to use it properly. Its sharper than sharp and a joy to use. I started taking macro shots of the bees that hang around my Lavender bushes. I then started using it as a walk around lens. I can't recommend this enough and it will sit on my new K1 most of the time..

Using this lens in 2 major situations: street portrait when WR needed, and jewelry packshots.
For portrait, love the bokeh. And sharpness. And blazing fast AF. An microcontrasts. everything . It delivers great shots in harsh climate conditions.
For jewelry packshots, it's amazing how it handles well the reflections and abberations, while working with glass type objects, differents metals aso. Allmost no PP needed.
And it's also a great lens all sharp at infinity focus.

I consider this lens to be overall at least equal to the limiteds and FA* , and i'm happy Pentax has a super price tag for it, given the amazing handling and performance.

Very good macro lens when stopped down a bit, usable as short telephoto portrait lens too. There are some aberrations visible when aperture is wide open. F4+ helps.

I'm missing some kind of focus limiter on this lens and also aperture ring would be nice to keep to retain back-compatibility with film bodies and also to enable users to mount lens on various tubes.

What can I say, this lens is awsome. What does this lens so good?

1. Size - it will always go with you, it doesn't take much space in your bag.

2. Build quality - This is a limited lens, it doesn't read like this in the box but can't see any difference with a limited lens. The WR makes this little gem usable with any clima conditions.

3. Sharpness - Nothing to add to the reputation of the 100mm macro from Pentax, it's razor sharp

4. Bokeh - The rounded blades makes a buttery and creamy bokeh, really great. I wonder how it will render in the K-1

This is really a must have on Pentax line up, sharp, compact, well built, WR......only it's price can be a stopper for some people, but quality has a price.

Some examples so you can judge it's quality and bokeh:
